Sintra is a SaaS startup - a digital assistant platform that combines multiple AI “helpers,” a central Brain AI knowledge base and several automation workflows. It is designed to streamline business processes ranging from customer support and copywriting to data analysis, recruitment and social media management. Each helper is specialized for a particular domain (e.g., Cassie handles support queries, Dexter performs data analysis, Penn writes copy). Users interact with helpers through chat-like conversations and can customize the tone, length and language of responses.
Who is Sintra designed for?
Sintra is designed for people wanting to:
Utilize AI to work more efficiently and save time without having technical knowledge.
Manage multiple businesses or projects in one place.
Manage their single business or project in a single place.
Our goal is to make work enjoyable by saving you time and teaching you how to leverage AI effectively.
When building Sintra, we think of small business owners, agencies and freelancers; however, it can be utilized by anyone working on their business, project or simply wanting to automate their workflows.
Key Features
Brain AI
A knowledge management module that stores snippets, webpages and media; it personalizes helper responses based on your business information and integrates with external accounts. Learn about Brain AI.
AI Helpers
12 helpers, each with a unique persona and skill set. They can draft emails, write blog posts, analyze data, brainstorm product ideas, perform SEO audits and more. Some helpers have automations that can run in the background and all of our helpers have their own set of power-ups that act as instant tasks. Learn about Sintra’s Helpers.
Automations
Automations are standalone workflows that operate outside of the chat environment. They run in the background after setup, later requiring minimal input from your side. On the Home page some helper cards show a zap icon badge in the top right corner; clicking that badge routes you to an automation setup page for that helper.Unlike power-ups, automations always require a setup process and rely on integrations. Learn about available automations.
Inbox & history
A unified inbox for tasks generated by helpers and automations - space to check as it requires your involvement. Plus, a history panel for past conversations with the Helpers.
